What effect does high density altitude, as compared to low density altitude, have on propeller efficiency and why?

0

Efficiency is reduced because the propeller exerts less force at high density altitudes than at low density altitudes. Efficiency is reduced due to the increased force of the propeller in the thinner air. Efficiency is increased due to less friction ...
